This adapter works with a linux kernel newer than 3.7 .

Making it Work: < linux 3.7.x

The Terratec Cinergy TStick RC HD works with Ambosa's RTL2832U driver
It won't find any channel with the included antenna, but when connected to
the aerial outlet (building antenna) it works fine with occassional square noise
or very short cuts (maybe more often in HD channels ???).

Can't test very often, because it's at a friend's, not mine.

I haven't found an email address to tell Ambrosa and I don't have
a GitHub account, maybe someone who has can send a link to the GitHub forum?

The system I tested is a Debian squeeze, with a custom compiled linux-libre 3.2.1.

Firmware

I haven't copied any firmware and I doubt linux-libre would have
loaded it. I think it works without any firmware file.
Didn't check if there is any firmware somehow embedded in the
source I compiled or it's simply shipped already on the usb stick.
